With `capture_locals=True`, `StackSummary.format` prints the local variables for every frame: https://github.com/python/cpython/blob/4827483f47906fecee6b5d9097df2a69a293a85c/Lib/traceback.py#L440 This will fail, however, if string conversion fails. StackSummary.format should be robust towards such possibilities. An easy fix would be a utility function: ``` def try_str(x): try: return str(x) except: return "<some sensible hint>" ```
